Description
Technical field
The present invention relates to silicon carbide smelting exhaust gas recovery systems, and more particularly, to silicon carbide smelting exhaust collection is flexible
Formula bonnet.
Background technique
Silicon carbide is also known as diamond dust, hardness between corundum and diamond, have high mechanical strength, thermal stability it is good,
The series of advantages such as acid-alkali-corrosive-resisting, anti-thermal shock be good, are widely applied to the fields such as grinding tool, smelting iron and steel, military project.China
It is that maximum country silicon carbide production and used, the country are commonly linear type for the type of furnace of silicon carbide smelting and fix in the world
Furnace.It can generate during silicon carbide smelting largely with CO gas as main component, while with a small amount of SO2The production of gas
It is raw.The fixed furnace length of linear type is longer, and exhaust collection is relatively difficult, and there are risk of explosion.Country's common practice is at present
The direct emission after furnace charge surface is by the gas ignition of spilling, lacks necessary gas gathering mask.It not only results in so uncombusted
CO and SO2It is discharged into atmosphere and pollutes environment, and dust from flying causes operating condition in workshop severe, while valuable gases CO
Burning causes the significant wastage of the energy.
There are two types of modes for the processing of silicon carbide smelting tail gas recycle：（1）It is collected to smelting after the gas generated is lighted, so
It concentrates afterwards and desulphurization and denitration processing is carried out to the tail gas of collection, discharged after up to standard；（2）Concentration receipts are carried out to the gas generated is smelted
Collection, by being comprehensively utilized after purified treatment to CO（Such as combustion power generation, production industrial chemicals）.But both
Take-back model common keypoints are the gas for how collecting silicon carbide smelting generation or the tail gas after burning.Its difficult point mainly exists
In：（1）Silicon carbide smelting furnace length is longer, and the flue gas area that sheds is larger, needs to make huge gas gathering mask；（2）Smelting process
Middle furnace charge head temperature is higher, and usually at 300 degrees Celsius or more, common gas gathering mask is difficult to apply under this operating condition；（3）It smelts
Contain CO in the tail gas of generation, there are the risks of explosion；（4）Sic smelting furnace generally uses in groups, usual 4 ~ 6 smelting furnaces
It is one group, is required according to smelting process, gas gathering mask is needed in smelting process, but carry out taking off furnace, come out of the stove and fill after the completion of smelting
When furnace, gas gathering mask allows for removing completely.Therefore, still unmature currently on the market to be used for silicon carbide smelting exhaust collection
Bonnet system.
Summary of the invention
It is an object of that present invention to provide a kind of telescopic bonnets for silicon carbide smelting exhaust collection, realize and adapt to high temperature
Environment conveniently moving, flexible foldable, occupies little space, invests small feature.
To achieve the above object, the present invention takes following technical proposals：
Telescopic bonnet of the present invention for silicon carbide smelting exhaust collection, consolidating including movable support and character "door" form structure
The bonnet face being fabricated from a flexible material on the bonnet frame is arranged in the bonnet frame that fixed rack is constituted；The movable support by

It is respectively and fixedly provided with the guide plate of character "door" form structure on each door shape frame, is spaced apart and is equipped on the guide plate
Multiple pilot holes are fixed with the first bonnet face of character "door" form structure positioned at guide plate in the plate face of the fixed bracket side
Braced frame；Be provided with guide rod between two neighboring guide plate, the guide rod far from support bracket fastened one end with it is corresponding
One guide plate is fixedly connected, and the other end of guide rod passes through the pilot hole on another corresponding guide plate and is fixed with a word
Second bonnet face braced frame of shape structure；The supporting sleeve is the telescopic structure being made of more piece casing, every section
Described sleeve pipe is fixedly connected with a corresponding second bonnet face braced frame respectively far from support bracket fastened one end, the section casing
The other end socket-connect with lower casing joint.
The invention has the advantages that realizing that silicon carbide smelting tail gas and shove charge take off the collection of dust during furnace, to production field
Ground require it is lower, it is easy to operate.Using telescopic structure form, space occupied is reduced, conveniently in groups between sic smelting furnace
It calls.Bonnet is made of flexible material, and light-weight, from steel quantity consumption is largely reduced, manufacturing cost is low, while even if
The urgent working of a furnace occurs（Such as tail gas explosion, spray furnace）, flexible material can pressure release quickly, be unlikely to cause disaster, and be easy to repair
It mends.In addition, temperature sensor and carbon monoxide detector are arranged on the pipe fitting that bonnet external support casing is connected, be conducive to ensure
Bonnet takes out smoke evacuation system and stablizes safe operation, can add video monitoring system inside bonnet when necessary, for smelting operating condition reality
When monitor.
